Addressing Soiling: From Interface Chemistry to Practicality

Close

Natural soiling has reduced the energy output of photovoltaic systems since the inception of the technology. Soiling is a complex problem that increases uncertainty and drives up the levelized cost of energy through lost energy production, increased operation and maintenance costs, and financing rates. This project is developing a predictive soiling model and a soiling rate map of the nation based on the available and, if necessary, additionally collected data and use it to provide operations and maintenance guidance to the industry.
